Linux and Shell Scripting Essentials

Introduction to Linux

Linux is an open-source OS modeled after UNIX. It is widely used for its stability, security, and customization options. It is developed by a global community, resulting in various distributions tailored to different needs.

Why Choose Linux?

Open Source: Free to use, modify, and distribute.
Security: Strong user permissions and regular updates.
Stability: Reliable and often used in servers.
Customization: Highly adaptable to user needs.
Community Support: Extensive documentation and support.

Understanding Virtual Machines

A virtual machine (VM) is software that emulates a computer system, allowing you to run an OS like Linux within another OS.

Key Components of a VM:

Hypervisor: Software that creates and runs VMs.
Type 1: Runs directly on hardware.
Type 2: Runs on the host OS.
Virtual CPU: Simulates a physical CPU.
Virtual Memory: Allocates host memory to the VM.
Virtual Storage: Uses host disk space for virtual disks.
Virtual Network: Provides network connectivity.
Understanding Linux and VMs is crucial for leveraging this versatile OS. For more detailed information, refer to the Notion link:
